T0 all whom it may concern:

Be it known that LLu'rnnR W. GRAYsoN, a citizen of the UnitedStates, and a resident of Youngstown, in the county of Maof Ohio, have invented a following is a full, tion. v

My invention relates to turbines or rotary engines to be operated by any suitable fluid under pressure.

The object of the\invention is to 4'provide a simple, strong and eiiicient turbine of the reversible type, and which is easily controlled. i

With the above and other objects in view, the nature of which will more fully appear as the description roceeds, the invention consists in the noveFconstruction, combination and arran ement of parts as herein fully described, illustrated and claimed.

, In the accompanying drawings, .fortuin part of the appllcation, similar characters o reference indicate corresponding parts in all the views, 'and Figure 1 is a vertical section of my invention on line 1-1, Fig. f2; Fig. 2 isla section on line 2 2, Fig. 1; Fig. 3 1s a perspective view of the rotor; Fig. 4 is a perspective view of one of the impinging blades of the rotor; Fig. 5 is a plan view on the rotor; Fig. 6 is a side elevation of the turbine; and Fi 7 is an elevation of my turbine provide with more than one fluid inlet.

Referring to the4 drawings, 8 represents the stator, which has two concentric, cylindrical sections 9 and 10 united in the central part of the facing lateral surfaces by a partition ll'forrning an annular recess 12 at each endof the stator. The stator 8 is rovided with an extension 13, forming a ase therefor, and also with lateral flanges 141- at the edge of the outer cylindrical sections 10. Closing the ends of the stator 8 are covers 15 bolted to the flanges 14 The covers have annular projections 16 fitting inte annular recesses 17 provided at the ends of clear, and exact descripthe cylindrical section 9-of the stator 8. The A annular recesses receive packing 18, which also engages'the annular projection 16, and

thus leaka e is prevented from the annular chambers ormed by the annular recesses 12 when the same are closed b the covers 1.5. Each of said annular cham ers has a fluid 'possibilityA of lthrust thereon lbythe motive fluid. s

inlet 19, preferably adjacent the base -of the stator.

Mounted within :the cylindrical section 9 between the covers 15 is a rotor 20 formed of a central disk 21 fittingly snugly into the cylindrical section, the hub 22 of the disk being keyed to a shaft 23 bearing in the covers 15. Between the periphery of the flange and the hub 22, and to each side of the flange, 'is a cylindrical section 24 integral with the flange. The edge of each of the cylindrical sections 24. bears a ainst the corresponding cover 15. The d1sk 21 is provided with impinging blades 25 extending transversal ofthe blade between the covers 15, and ra ial of they flan e, from the cylindrical sections 24 towar the periphery of the flange. These blades 25 can be made integral with the flange, but, preferably, they are removable from the flange, and are in the shape best shown in Fig. 4.' The impinging side 26A of the blade is depressed toward the upper edge of the blade, as shown in 24,

so that a shoulder 27 is formed on each side of the blade, which is adapted to engage the side of the flange when the blade is orced into position on the flan e, and this shoulder being on the opposite si e of the impinging face it helps-to withstand the thrust of the fluid pressure acting against it. ,The blade 25 has also at the bottom thereof pins k28 adapted to engage corresponding openings in the lateral surface of thel corres onding cylindrical section 24, whereby the lade is not only keyed tothe flange but to the cylindrical'section also, thereby diminishing the injury to the blade from the It will be noted that the impinging surfaces 26 of each blade 25 are on opposite sides of the blade and are positioned on the opposite sides of the 21, so as to receive the motive fluid from opposite directions.

' For this purpose the lateral surfaceof the cylindrical section 9 of the stator 8 1s provided with two series of nozzles 29 and 30.V

The 'series of nozzles 29 iscentral with one side of the impinging surfaces y26; and the nozzles 30.,.with the other 51de of the 1mpinging surfaces of the blades 25. Each of said series of nozzles is provided with the correspondin Vfluid inlet 19, as previously he outlet for the motive fluid, after it hasfperformed its work, is obtained atA by providing. notches 31 in the edges 6ft-the `cylmdrical sections 24 between the lades 25.

The bottoms A`,of Isaid 'notches- Preferably arcuated, the notch being deepest at impinging face of the blade and gradually decreasing in depth as it approaches theiol lowing blade, preferably the notch not exteridingt .theifdlow'mg 'blade. .1F-rom. Eig; 5 it will be seen that the notches 31 on opposite sides of the cylindrical"' section "24 are ,dirfefizppwsitely- By forming the notches as state the motive fluid coming from .the nozales 2 9 or 30 must first act on'tlie face 26 of the'blade` 25, from where :it isA ilected,and finds'l an outlet through the'fntclii 31Qinto the cylindrical section '24',- The two cylindrical sections-24' are brought intoxior'nmunicatio by POYding ,apertures 32 in the disk 21. .f In o ne of Athe covers 1.5 an outlet,3 3 isv provided, rso thatthemorked motive fluid finds its escape .throughvfsaid outlet 33, whether it fcomes fmn1one. orfthe other side of therotor. l .131, vthe turbine is shown l'v v ii', h' three inotiyef- Uuidlinlets 19.- to each o f the annu.- laa-,hamhers iformed' by the annulary rel f,- I, i Fjigorrn'the zforegoing description, taken in {PQQRIQCQQQ :.Mgith 4 the accompanying drawingggthe@ vant eof 'the construction and 0,11?ration` of the. uevict1 shown will be readily .understood ha these, Skills-1A in the art 60 which theimfention prtagl's and While.
